An upper level high (Shaded “Arch” shape with blue arrows will clear the skies a bit for your Thursday and then another upper level low pressure trough (Shaded “U” shape with blue arrows) will return clouds and rain through the weekend. Another frontal system (Position shown is Sunday) will help keep us wet through the Easter weekend. The Full “Pink” Moon occurs at 5:06 AM Saturday and there will be a total Lunar Eclipse that will be visible in the Pacific Northwest just before dawn. By the look of it a thick cloud cover will be obscuring our view of the moon, but if the clouds do open it is safe to look directly at the Lunar Eclipse.
